Ok finally got on the dyno. Used some of the advice given here when I dailed the cams. The power numbers are okay, but we could probably get a few more hp from this motor. Main concern is the power peaks too soon. This is on a stock IM. We're gonna build a custom plenum and see if that helps the motor breath better at higher rpm. thoughts?
